Why do my plants get white spotty mold on the leaves & how do I fix it?

If you are seeing powder mold, most types are toxic to inhale, so be careful. If you already have it, there are a number of organic products to use. Serenade is one I’ve used and it works great, I’d use few applications. If you have powder mold reoccurring regularly, try increasing your airflow to drop the humidity. Conidia thrive in temperatures 55-95 degrees so changing the temperature is not really a solution. In an indoor environment, the best preventative is a sulfur burner. When the sulfur evaporates, surfaces in the environment are at a pH that the mold cannot grow in. If your plants grow very quickly, I recommend giving two dosages. For flowering plants, do not use a sulfur evaporator after the second week. The sulphur smell tends to stick around for weeks and could taint the smell of your fruit or flowers.
